The PSS Shaft Seal is the number one selling marine mechanical seal
worldwide and is installed as standard equipment by many of the worlds most
reputable boat builders / yards. The PSS Shaft Seal is also recognized as
the premiere retrofit (aftermarket) seal on the world market. Certified by
Bureau Veritas, ABS & Rina: Boat builders / yards recognize the advantages
and value of installing the PSS as it eliminates the maintenance, constant
adjustment & cost associated with traditional packing type glands. Aside
from these benefits, the PSS Shaft Seal helps to eliminate water in the
bilge (100% water tight) & wear to the propeller shaft. The PSS Shaft Seal
can be easily retrofitted and is available for shafts ranging from 3/4"
(20mm) to 6" (150mm).
The PSS Shaft Seal is a mechanical face seal that is created between
the flat surfaces of the rotating stainless steel rotor and the stationary
carbon flange. The stationary carbon flange is attached to the vessels stern tube with hose clamps and the carbon flange is attached to the front side of the bellows with hose clamps. The stainless steel rotor is fit on the shaft
in front of the carbon flange. The stainless steel rotor is used to compress the bellows before the collar is secured to the shaft with set-screws. This
compression (pre-load) maintains contact between the faces and allows the
PSS to compensate for the thrust from the propeller. The carbon flange is
bored larger than the shaft diameter allowing it to "float" around the shaft and thus compensate for most misalignment and vibration problems. The
stainless steel collar is sealed to the shaft by two o-rings that are
recessed into the bore of the collar. These o-rings rotate with the shaft
and stainless steel rotor and do not experience wear during operation.
**As with any rubber hose below waterline, the PSS bellows must be inspected on a regular basis for any sign of wear, aging or chemical deterioration.
PYI suggests as preventative maintenance that the PSS bellow be replaced in
six year intervals. During bellows replacement it is recommended the o-rings & set screws in the stainless steel rotor also be replaced."
Bellows may need to be more frequently inspected in an environment where
non-sealed batteries emit sulfuric acid. Sulfuric acid vapor will accelerate rubber deterioration, as will an ozonater.
The Maintenance Kit includes the items you need to properly maintain your
PSS Shaft Seal. Included in the kit is one (1) PSS bellow, two (2) O-rings,
five (5) set screws, four (4) new hose clamps and an allen key.

This has been handy
Format: Paperback
I am a new Nurse Practitioner working in an urgent care, often on my own. This has been an excellent resource. Who knew someone with a dog bite on their tongue would come in.

Great book
Format: Paperback
I worked in a setting where I was the only nurse for hundreds of inmates in a Max prison. I used this book to assist me in providing care to patients with their emergencies. It helped me decide how to handle situations where I had to intelligently explain a medical issue to a on call MD or chart in a correct manner. This was my own personal book and glad to have it. I believe I initially found the title from a ER MD who recommended it. This is the updated copy, I gave my old copy to a non medical neighbor who found it useful.

I'm a PA and work in Immediate care, this is a great reference book for procedures! Especially those that you don't do daily and need a refresher on before proceeding. I would highly recommend - it is well written, thorough, and covers procedural skills as well as treatments and different options to consider.

Nancy Pearcey finds true toxicity in the war on men!
Format: Hardcover
Nancy Pearcey has done it again. This work will prove to be a harbinger for a re-evaluation of the war on masculinity current in the Western world. Many are joining the bandwagon and spouting the mantras of "toxic masculinity." Particularly, that breed of “manhood,’ which is perceived to have its origins in the Church, is quite repugnant. Pearcey turns the tables on these folks to show that toxicity is, in reality, their own atmosphere of existence.
With the use of widespread research and surprising statistics, Nancy Pearcey has provided in this volume a veritable course in gender issues. The work includes history, cultural evaluation, biblical insight, philosophical sophistication, and balanced classical apologetics. Far from being a partisan theological tirade, the book will bring needed clarity to people on various points on the spectrum.
At the core of her thesis is distinguishing the authentic manly characteristics that throughout history have been applauded and found so necessary for the flourishing of Western civilization in contrast to the bravado and supposed "real man" macho type that is the stereotypical target of the so-called feminists. Here, in particular, Pearcey uncovers acute analysis and recorded available statistics for any that would do the spadework. For example, from the research of one study, entitled 'The Pentecostal Gender Paradox,' she shows "that evangelical forms of Christianity benefit women by 'morally restraining the traditional autonomy of the male and the selfish or irresponsible exercise of male power' " In another study, published in the New York Times, it was concluded that "the happiest of all wives in America are religious conservatives . . . Fully seventy percent of wives who hold conservative gender values and attend religious services regularly with their husbands have high quality marriages." Pearcey is so enthralled, she says, "Did you catch that? Let me repeat it . . ." In addition, the satisfaction that women in this demographic have extends to the bedroom as well. Due to these widespread findings, Pearcey says, citing Brad Wilcox, "Academics need to cast aside their prejudices about religious conservatives and evangelicals in particular." A telling conclusion!
In this reviewer's opinion, the chapter on the Pioneers and Puritans was outstanding. No spoiler alert. Get the book and read it for yourself. This chapter alone is worth the cost of purchase.
The discussion on the industrial age and the transition for men to become absentee fathers was a helpful reminder that political and economic emancipation brings with it some unexpected consequences. The Father, as the provider, now becomes engaged in a manner of individual competition for prestige and advancement. No longer surrounded by loved ones in a struggle to eke out a living in an agrarian world, the industrialization process reduced men to cogs in a machine. Profit for the owners of the means of wealth production, the proverbial bottom line, now was all that really mattered. As Pearcey elegantly puts it, "The new workplace fostered an economic philosophy of individualism, where workers were treated as so many interchangeable units to be plugged into the production process, each struggling to advance himself at the expense of others." Most importantly, Pearcey catches that underlying and emerging contrast in the following comment, ". . . the conflict between work and family did not involve just juggling time demands but also transitioning between two contrasting sets of character traits." Here also, Pearcey draws on her prior book Total Truth to examine the resultant separation of spheres where men began functioning differently in actual practice depending on what and where they were acting out their divided lives.
There is so much ground covered in this fine work. I cannot recommend it highly enough. No doubt, as this reviewer found the occasional issue that would be worded differently or even contrastingly, the bulk of the book is endorsed wholeheartedly.
Thank you, Nancy Pearcey for another book that will become a classic.
I had received access to a pre-published edition of the book. I was under no compulsion to give a favorable assessment.
Theodore Zachariades.
